A new 3.5 updated was released yesterday (June 7) which fixes a serious bug related to the way the new loader code was being generated for some pages.
If you have had problems trying to get the relative configuration to work, try this new update.
You should recompile and update the loader in order to properly update your menus.
Forgot to mention that this release also fixes two bugs:
- Groups height and width will now be properly determined when using several separators on the same group.
- Toolbar items are now properly aligned (vertically) inside their box.
Also, the offset parameters of the Tools->Toolbar Editor->Positioning dialog now accept negative values.
